Embodiment Construction

[0018]FIG. 1 is a system diagram illustrating a premises serviced by a Powerline Communication (PLC) device constructed according to one or more embodiments of the present invention. Referring to FIG. 1, the premises 100 typically has a distributed mains wiring system (shown in heavy black line) consisting of one or more ring mains, several stubs and some distribution back to a junction box 101. In other constructs the distributed mains wiring system has a breaker box with circuits routed there from in a star configuration. With the example of FIG. 1, the premises is a coffee shop, book store, restaurant, or another retail establishment in which customers spend some time. The owner of the establishment derives income from customers that spend time in the establishment. Thus, the owner desires to provide Internet access to its customers.

[0019]Each of the customers receives Internet access via a Wireless Local Area Network (WLAN) setup by the premises owner. In the example illustrated...

Abstract

A Power Line Communications (PLC) device includes a processing module, memory, a Wireless Local Area Network interface (WLAN I/F), and a PLC communication interface (PLC I/F). When operating as a client device, the PLC device establishes communications with a premises communication device via the PLC I/F, requests WLAN service from the premises communication device via the PLC I/F, receives WLAN access credentials from the premises communication device via the PLC I/F, and accesses a WLAN via the WLAN I/F using the WLAN access credentials. The PLC device communicates with a client device via the PLC I/F, receives a WLAN service request from the client device via the PLC I/F, validates the client device for WLAN service, and transmits WLAN access credentials to the client device via the PLC I/F. The PLC device may also support backchannel operations such as financial transactions, key exchanges, encryption support, all via the PLC I/F.
